DYNAMO-ELECTRIC RAILWAY-BRAKE.

SPECIFICATION forming part of Letters Patent No. 347,904, clatedAugust24, 1886.

Application filed April 28, 1886. Serial No. 200,459.

Improvements in Dynamo-Electric Railway- Brakes, of which the followingis a description.

The present invention relates to improvements in railway-brakes of theclass that are actuated and controlled by electrically-driven apparatus;and it consists in an improved system of connecting and operating thebrake mechanism, whereby all the brakes on a train can be operated fromone point, the details of the construction, arrangement, and operationwhereof will be more fully hereinafter set forth.

In the accompanying drawings, which form part of this application,Figure 1 is a general plan view showing the runninggear of a car and amotorear connected thereto, the two cars together illustrating thecontinuity of the brake mechanism. Fig. 2 is an elevation of an electricmotor arranged to operate the system of brakes.

Similar letters denote like parts throughout.

A and B represent the trucks at opposite ends of an ordinary railway caror coach, and a and b, in dotted lines, the end platforms thereof, whichare, as shown, provided with hand brake-operating devices, as usual.

0 and D are the systems of rods and levers by which the brake-beams E Eare controlled and the brake-shoes applied to the wheels.

The brake mechanism on the trucks A and B is connected in the usual andwell-known manner,- but instead of the main rods 6 e being connecteddirectly to the hand mechanism, they are connected to each other throughout the train, additional rods and chains, F F, being connectedthereto at any suitable point, and, diverging therefrom, are secured tothe hand brake-operating mechanism, so that the last car in the trainmay have a fixed point against which the force applying the brake can beexerted, and also that the cars may be handled in the usual manner whendetached. G is a second car, which, for eonvenience,:I have called themotorcar, and may be placed at either end of the train, as found mostdesirable. As shown,'it comprises only one set of wheels, but may, ofcourse, be similar in (No model.)

construction to the rest of the train, and it is provided withbrake-beams E and a set of brake-rods and connections, 0, the latter ofwhich is connected by its inner rod or member, cl, directly to mechanismacted upon by the motor H, carried upon said'car, from which it will beunderstood that when the motor is rotated in one direction all thebrakes on the entire train will be set thereby, each system .pullingupon the next, and so on throughout.

In Fig. 2, I represents the floor or platform upon the car G, belowwhich the motor H is mounted. The motor itself may be of any wellknownconstruction, being preferably similar to the one shown and described inapplication for Letters Patent filed by me March 15, 1886, Serial No.195,212. Asuitable handle, J, is provided at the forward end of themotor, whereby the com mutator-brushes I and N can be moved as desired,and the direction of rotation and rotation thereof can be controlledthereby. The rear end of the armature-shaft j is connected directly to ascrewshaft, M, which works into a threaded headblock, 0, which issupported upon aguide, Q, fixed between depending arms or braces R It,secured below the platform I. A link, S, passes through or around thesupport R and is securely fixed or connected at its outer end to theblock 0, which travels horizontally upon the serew-shaft and itssupport, and at the other end to the terminal (I of the brake mechanism.It will be apparent'that rotation of the armature of the motor willcause the block 0 to move horizontally along the guide Qand 'to act uponthe brake connection (1, setting or releasing the system of brakes, asmay be desired.

' The electric connections by which the motor is operated may be of anydesired character including any independent source of supply that may becarried by the train for other purposes.

I do not desire to limit myself to the exact details of construction andarrangement herein shown and described, as the apparatus may be modifiedin many ways without departing from the spirit of the invention.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-
